Since it's more than 25k characters, I'll just use Pastebin for it. Enjoy. Again, not all will work, some may be disabled while cooking by DTG, for example, probably the Vulkan related ones. I did not test all of them out yet, as it's too many, lol. Link: TSW2 render engine commands & settings list - Pastebin.com
This is pretty useless. You only mention the r. commands, but there are many others as well that are TSW2 specific.
